The invention relates to a combined type dedusting sound-insulating air suction filter device which is characterized by being arranged on a ventilation opening on indoor and outdoor wall bodies of a civil building to implement natural ventilation and air change, having no energy consumption when the civil building is in a state of good sealing performance, leading outdoor air containing moisture, dust and noises into a room by utilizing the pressure difference of indoor and outdoor air as driving force and also carrying out the filtering and repeated purification processing of the dehumidification, the dedusting, the filtering, the purification, the sound absorption and the noise reduction of a three-layer dedusting filter cloth and a second-stage filtering dedusting purification device. The invention has simple, compact and reasonable structure, reasonably utilizes the natural resources to achieve the dehumidification efficiency of 50 percent, the dedusting effect of 90 percent, the dedusting grain diameter smaller or equal to 10 micrometers, the noise reduction capability of 35 dB, sufficiently improves the indoor air quality, reduces the harm of indoor and outdoor air pollution on human health and achieves the outstanding advantages of energy saving, environmental protection and carbon-free discharge of the civil building.
Description
technical field [0001] A composite dust-removing and sound-insulating air intake filter device of the present invention relates to natural ventilation and air exchange implemented on ventilation openings set up on indoor and outdoor walls of civil buildings in humid and northern and southern regions, without energy consumption and utilizing indoor and outdoor atmosphere The pressure difference is used as the driving force to filter and purify the air containing moisture, dust and noise in the outdoor air pollution, sound absorption and noise reduction, building energy saving and carbon-free environmental protection. Background technique [0002] The main causes of outdoor air pollution are exhaust emissions from diesel engine passenger trucks running on the road, moisture, dust, and noise emitted by factories, mines, enterprises, and building construction. The main cause of indoor air pollution in buildings is that harmful gases such as formaldehyde, benzene, and volatile ch...
